We’re constantly focused on bringing new advertisers and more advertising spend to AdSense sites. One way to do so is to make it easier for brand advertisers to reach their goals on AdSense sites. Brand advertisers are focused on raising brand awareness and driving engagement, typically with display ads, for a product or service a person may buy in the future. Brand advertisers differ from direct response advertisers, who typically look for clicks and conversions from the campaigns they run on your site.

For example, an advertiser selling DVDs online may want users to click through and make purchases, while a brand advertiser for an upcoming summer blockbuster may want to generate awareness among users. Because of their campaign goals, brand advertisers tend to be more selective about the sites their ads run on, as well as where on the page their ads appear. We want to help these new advertisers compete for the portions of your ad space that are most attractive to them so that we can increase your earnings over time.

With that in mind, we're launching a new beta advertiser feature that we believe will help accomplish this goal. The new feature enables brand advertisers to target their ads to ad units that are immediately visible when a page is loaded -- in other words, the portions of the page a user can see without needing to scroll down. The ads that are immediately visible are called 'above the fold'; those that require a user to scroll down in order to be seen are called 'below the fold.'

In order to determine which ads are above and below the fold, we've implemented a statistically-driven model. The model takes into account various user experiences and situations, including different web browsers, monitor sizes, and screen resolutions, and only considers ads above the fold if they are fully on-screen when the browser window loads.

If you've placed your ad units above the fold, advertisers using this feature will now be able to reach your site in a new way. If you haven't, placing new ad units above the fold will enable them to do so. We believe this feature will help attract new brand campaigns to AdSense sites, bringing more revenue to publishers over time.
